why not just do one of those fuel tanks in the bed of your truck.. that way you don't need all the cans?

i have about a dozen cans, bought and paid for, easy to use, i fill them, they go in my garage, fill the mowers each morning, only a 2 gal mixed can for trimmers stays in the trucks.

ive thought about the one in the truck but i dont know what the DOT laws are about carring that much gasoline in a bed without placards. in not in the mood to deal with that. i wanted the tank in the yard to fill the diesel in the trucks. that would be nice
